Re: Java ComboBox not updating

Here's an example of an if statement in a JComboBox change listener I wrote that does what you've described. Let me know if you have questions or would like to see the if statement in action. Perhaps you could show your code in action first.

// selectedIndex is the selected index of the JComboBox being watched// by the listener. the program varies a second JComboBox based on// the selection in the first JComboBoxif( selectedIndex >=1&& selectedIndex <5){// obtain the second JComboBox' model to modify its contents
DefaultComboBoxModel<String> model =(DefaultComboBoxModel)comboBox2.getModel();// remove all elements
model.removeAllElements();// magic number 4 is 4 choices per indexfor(int i =0; i < selectedIndex *4; i++){
model.addElement(""+(char)('A'+ i ));}}
